The refrigerator 1 may further include a dispenser 40. The dispenser 40 may be built in the door 300. For example, the dispenser 40 may be built in the top left door 300 a. In the following description, assume that the dispenser 40 is built in the top left door 300 a. The user may take water or ice out directly through the dispenser 40 without opening the door 300 a. The dispenser 40 may include a cavity 41 sunken inwardly from the door 300 a to form a take-out space. In the cavity 41, there may be a take-out hole (not shown) through which water or ice comes out, and a take-out lever 42 to take the water or ice out. When the take-out lever 42 is pressed, water or ice comes out from the take-out hole. The dispenser 40 may further include a dispenser state display window 43 for displaying a state of operation of the dispenser 40. The dispenser state display window 43 may have a touch function.

The refrigerator 1 may further include a display unit 200.

The display unit 200 may be built in the door 300 for the user convenience. Specifically, the display unit 200 may be installed on the front side 301 of the door 300. Although FIGS. 1 and 2 show the display unit 200 installed on a top right door 300 b, the display unit 200 may be installed at any place on any door 300 without being limited to the top right door 300 b. In the following description, assume that the display unit 200 is built in the top right door 300 b.

A top end 201 of the display unit 200 may be aligned with a top end 101 of the handle 100 in the up-and-down direction Z of the door 300. A bottom end 202 of the display unit 200 may be aligned with a bottom end 44 of the dispenser 40 in the up-and-down direction Z of the door 300. One side end 203 b of the display unit 200 adjacent to the handle 100 may be separated by a certain distance from the handle 100. The other side end 203 a opposite of the one side end 203 b of the display unit 200 adjacent to the handle 100 may be separated by a certain distance from the edge of the door 300.

To put it from a different perspective, the display unit 200 may have a rectangular form with elongated sides in the up-and-down direction Z of the door 300. The display unit 200 may include a right long side 203 a directed toward the right of the door 300, a left long side 203 b directed toward the left of the door 300, a top short side 201 directed toward the top of the door 300, and a bottom short side 202 directed toward the bottom of the door 300. The right long side 203 a may be separated by a certain distance from the right edge of the door 300 in the left direction of the door 300. The left long side 203 b may be separated by a certain distance from the handle 100 in the right direction of the door 100. The top short side 201 may be aligned with the top end 101 of the handle 100 in the up-and-down direction Z of the door 300. The bottom short side 202 may be aligned with the bottom end 44 of the dispenser 40 in the up-and-down direction Z of the door 300.

This arrangement of the display unit 200 may realize a sharp and stable design of the refrigerator 1. In describing such arrangement relations among the display unit 200, the dispenser 40, and the handle 100, the display unit 200 may be used in the same sense as the display glass 220.

The display unit 200 may have a wakeup function automatically activated when the user approaches to within a certain range. The wakeup function may be implemented by a proximity detection sensor 50 (see FIG. 5). Specifically, as shown in FIG. 2, when the proximity detection sensor 50 detects a user approaching to within a certain range, the display unit 200 is activated. In other words, the display unit 200 is in the ON state. On the other hand, as shown in FIG. 1, when no approach of the user is detected within the certain range by the proximity detection sensor 50, the display unit 200 is not activated. In other words, the display unit 200 is in the OFF state. Once the display unit 200 is activated, various videos or images may be displayed on a display 210.

The display unit 200 will be described in more detail later.

FIG. 4 is a perspective view of a door of a refrigerator with a display built in the door, according to an embodiment of the present disclosure, and FIG. 5 is a perspective view of a door of a refrigerator with a display glass removed therefrom to show a first example of the arrangement of embedded structures, according to an embodiment of the present disclosure. In the following description, a door refers to a door with the display unit 200 built therein, i.e., the top right door 300 b. In FIG. 5, a combining cover 260 is omitted.

As shown in FIGS. 4 and 5, the display unit 200 may include the display 210 for displaying images or videos. The display 210 may further include a Liquid Crystal Display (LCD).

The display unit 200 may further include the display glass 220.

The display glass 220 may be located on the front of the display 210. A touch screen 221 may be formed on the display glass 220.

How to form the touch screen 221 on the display glass 220 is as follows:

A deposited film is attached on the rear side of the display glass 220 that faces the display 210. After that, the rear side of the display glass 220 is printed in order to prevent internal components of the display unit 200 from being exposed through the display glass 220. Specifically, to shield the internal components and assembling structures of the display unit 200, edges of the rear side of the display glass are printed. A first area 222, as will be described later, may not be printed for the user to see an image or video displayed on the display 210. On the other hand, a second area 223 may be printed for shielding. After the printing process, a touch film is attached on the rear side of the display glass 220.

Another way of forming the touch screen 221 on the display glass 220 is as follows:

A polaroid film is attached on the rear side of the display glass 220 that faces the display 210. After that, edges of the rear side of the display glass 220 are printed in order to prevent the internal components or assembling structures of the display unit 200 from being exposed through the display glass 220. As described above, the first area 222 may not be printed while the second area 223 may be printed. After the printing process, a touch film is attached on the rear side of the display glass 220.

The touch screen 221 may be implemented to have an electrostatic type or a resistive type.

The way of forming the touch screen 221 is, however, not limited to the example.

The display glass 220 may have an area larger than the display 210. As such, using the display glass 220 having an area larger than the display 210 may secure a room for placing extra components without encroaching on the display 210.

To put this from a different perspective, the display glass 220 may include the first area 222 and the second area 223.

The first area 222 may be an area corresponding to the display 210.

The second area 223 may be an area other than the first area 222. Since the second area 223 is shielded through the printing process, various components may be arranged behind the second area 223. The arrangement relations among the various components will be described in more detail later.

At least one input icon may be placed on the display glass 220. The at least one input icon may include, for example, a camera icon 70 a to run a camera 60, a list icon 70 b to arrange various lists related to functions of the refrigerator 1, a home icon 70 c to go back to a start screen, a back icon 70 d to go back to the previous stage, and an information icon 70 e to provide information about overall functions of the refrigerator 1 or the display unit 200.

The at least one input icon may be formed on the display glass 220. Preferably, the at least one input icon may be formed in the second area 223 below the first area 222 so as to not interfere with the image or video displayed on the display 210.

The refrigerator 1 may further include the proximity detection sensor 50 for activating the display 210 when determining approaching of the user by detecting whether the user is approaching. If the user approaches to within a certain range, the proximity detection sensor 50 detects the approaching of the user and sends the detection signal to a microcomputer 90, which in turn activates the display 210.

The refrigerator 1 may further include a communication module 80. With the communication module 80, the refrigerator 1 may access the Internet. The refrigerator 1 with the communication module 80 may surf the Internet using the touch screen 221. Furthermore, the refrigerator 1 with the communication module 80 may receive a control command from outside over the Internet. Moreover, if at least one home appliance is connected over a network, the refrigerator with the communication module 80 may also serve as a home network server for performing centralized control over the at least one home appliance. In other words, the refrigerator 1 with the communication module 80 may allow the user to enter an Internet command or control command for the refrigerator 1 by manipulating the touch screen 221. The Internet command or the control command for the refrigerator 1 entered through the touch screen 221 is forwarded to the microcomputer 90, which in turn displays a web page connected over the Internet or a result of processing the control command on the display 210. The communication module 80 may include, for example, at least one of Wi-Fi, Bluetooth, Zigbee, and Z-wave.

The refrigerator 1 may further include a camera 60 capable of taking pictures of people or things. An image or video taken by the camera 60 is displayed on the display 210.

The refrigerator 1 may further include at least one microphone 85 to implement a voice recognition function. A voice command input through the at least one microphone 85 is sent to the microcomputer 90, which in turn controls the display 210 to display a result of the voice command.

The refrigerator 1 may further include an illumination sensor 55. The illumination sensor 55 may adjust lighting of the display 210 to be brighter under a bright condition and darker under a dark condition, thereby reducing power loss of the refrigerator 1. The detection result of the illuminating sensor 55 is sent to the microcomputer 90, and the microcomputer 90 controls the display 210 to adjust the lighting of the display 210.

At least one of the proximity detection sensor 50, the communication module 80, the camera 60, at least one of the microphone 85 and the illumination sensor 55 may be arranged behind the display glass 220. Specifically, at least one of the proximity detection sensor 50, the communication module 80, the camera 60, at least one of the microphone 85 and the illumination sensor 55 may be arranged behind the second area 223 of the display glass 220 to face the second area 223 of the display glass 220. Especially, it is desirable for the communication module 80 for transmitting and receiving electromagnetic waves to be arranged behind the second area 223 of the display glass 220. This is because the communication module 80 may have difficulty in transmitting and receiving electromagnetic waves when arranged behind the metal door frame 310, because the metal door frame 310 may block the electromagnetic waves.

At least one of the proximity detection sensor 50, the communication module 80, the camera 60, at least one of the microphone 85 and the illumination sensor 55 may be arranged on the front of the display case 230 that faces the display glass 220.

In the following description, assume that all of the proximity detection sensor 50, the communication module 80, the camera 60, at least one of the microphone 85 and the illumination sensor 55 are arranged on the front of the display case 230 to be located behind the second area 223 of the display glass 220.

As shown in FIG. 5, the proximity detection sensor 50, the communication module 80, the camera 60, at least one of the microphone 85 and the illumination sensor 55 may be arranged on the front of the display case 230 to be located below the display 210. The camera 60 may be arranged on the left of the display case 230 to be adjacent to the display 210. The communication module 80 may be arranged on the right of the display case 230 to be adjacent to the display 210. The proximity detection sensor 50 and the illumination sensor 55 may be arranged among at least one microphone 85. The at least one microphone 85 refers to a plurality of microphones. The proximity detection sensor 50, the illumination sensor 55, and the at least one microphone 85 may be arranged in the bottom part of the display case 230. Especially, the proximity detection sensor 50 may be arranged on the front bottom part of the display case 230 to be located under the display 210. The reason why it is desirable to arrange the proximity detection sensor 50 in the front bottom part of the display case 230 is to even detect whether a user having small height like a child is approaching.

At least one of the proximity detection sensor 50, the communication module 80, the camera 60, at least one of the microphone 85 and the illumination sensor 55 may be arranged under at least one input icon. Specifically, the at least one input icon may be formed in the second area 223 to be located between the first area 222 and at least one of the proximity detection sensor 50, the communication module 80, the camera 60, at least one of the microphone 85 and the illumination sensor 55 in the up-and-down direction Z of the door 300. The arrangement of the at least one input icon is not, however, limited to the example, but may be modified in various ways.
